We would like to thank Drs. Brilakis and Banerjee for their interest in our study (1). In our extensive experience (1,2), we have never had any relevant complications, especially atrial or ventricular fibrillation, with adenosine administration in the right coronary artery. This is consistent with data shown by other authors (3).
As stated in our paper (1), we had to stop the protocol in 4 patients due to atrioventricular block that technically hampered the evaluation of fractional flow reserve. Therefore, we believe that it is not worthwhile to increase the dose of adenosine in the evaluation of fractional flow reserve when there is already a relevant atrioventricular block with a low dose.
